FOOD-STEAM ER.

SPECIFICATION forming part of Letters Patent No. 476,247, dated June 7, 1892. Application filed January 21, 1892. Serial No. 41 ,35 (N 111 1 1 To all whom it may concern.-

Be it known that l, THOMAS OASCADEN, J r., a citizen of the United States of America, residing at Waterloo, in the county of Black Hawk and State of Iowa, have invented certain new and useful Improvements in Food- Steamers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in food-steamers or agricultural boilers.

The object of the invention is to provide a device which can be utilized for heating water and cooking food for live stock and which is susceptible of being used with either wood or coal as fuel; and the invention consists in providing a base with two doorways on opposite sides, one of which is adapted to receive wood and the other coal, such base being provided with a reversible rim, which forms the kettle-support and is adapted to receive a pipe through which the products of combustion escape, the kettle having a rim secured thereto, which forms an extension to which asectional top is secured by means of the same bolts which secure the rim to the body of the kettle, as will be hereinafter more fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure 1 is a vertical sectional view of a feed-boiler constructed in accordance with my invention. Fig. 2 isa sectional view of the furnace. Fig. 3 is a plan view of the furnace.

A designates the furnace, which is suitably supported on legs and provided with a firebox B and ash-pit b. The upper walls of the fire-box are extended outward and connect with a grooved ring or flange 0, having aninwardly-projecting portion 0, which abuts or fits closely against the lower part of the kettle D. The fire-box is provided with a suitable grate-support, so that the grate can rest immediately above the ash-pit I) when wood is used as fuel, and may be supported at a higher elevation when coal is used, thus providing means for securing the grate at different elevations. The ash-pit extends beyond the firebox to provide an air-passage 0L, which leads under the grate, said air-passage having the usual damper, as shown. The fire-box is provided at one end with a doorway e, which is covered by a suitable swinging door having the usual dampers. Opposite the door 6 the cylindrical portion of the furnace is provided with a throat f, and the side walls extend outward at an angle to form an inclined chute f','to the outer end of which is hinged a door g. This door when closed rests upon a flange formed on the rim G, and may have dampers and suitable catches for holding the same closed.

It will be observed that the inwardly-pro jecting flange c, hereinbetore referred to, is cut away or terminates adjacent to the throat or flue f, and that when the kettle is put in place and the furnace arranged as shown in Fig. 2 the products of combustion will be retained below the rim or flange c and pass through the throat-f bet-ween the ends of the inwardly-projecting rim 0, and from there around the body of the kettle to the chimney.

Edesignatestheupperportion of thefurnace, which consists of a ring having formed thereon a projecting portion it, said rim being cut away at h to form communication with the projecting portion which receives the Stovepipe. The upper edge of the portion E projects inward to form a rest for the flange of the kettle D, and it will be noted that this rim rests in a groove and is reversible, so that the projecting portion h, to which the chimney is attached, can be placed either on the same side of the furnace as the door 6 or on the side with the throat f.

The kettle D has a band or extension ring I, secured thereto by means of bolts 2' said bolts also serving to retain a section of the cover I thereon, to which the other section is hinged.

By means of the construction hereinbefore described I provide a furnace or agricultural boiler which is simple in construction and which can be readily used for burning different' kinds of fuel, and in which the products of combustion or heat given from the fuel first contacts with the bottom of the kettle or boiler and afterward in a reverse direction with the sides thereof before passing into the chimney.

The arrangement of the flues are the same whether used for coal or wood, said arrangement being accomplished by reversing the rim E, which carries the chimney. It will also be observed that the outwardly-flared plate f forms a convenient chute forfeeding coal to the fire-box.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. In an agricultural boiler, the combination of a fire-box carrying an outwardly and upwardly flared portion having a peripheral groove, an inwardly-proj ecting flange c,wl1icl1 terminates to form a throat, a reversible rim having an outwardly projecting portion adapted to receive a pipe, and doorways in the lower portion of the furnace located opposite each other, substantially as shown, and for the purpose set forth.

2. The combination, in an agricultural boiler 01' food-steamer, of a base A, having doorways for feeding prising a fuel-box having fuel thereto located opposite each other, a reversible rim mounted on the upper part of the furnace and provided with an exhaust-opening for the products of combustion, and a kettle mounted thereon, substantially as shown, and for the purpose set forth.

3. The combination, with a base A, comdoorways opposite each other leading thereto and on different planes, an inwardly-projecting flange c, and reversible rimE, mounted on the base beyond said flange, of a kettle D, adapted to be supported by the reversible rim and abut against the inwardly-projecting flange, said flange terminating so as to form a throat, substantially as shown, and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
